Claims

[Scope of utility model registration request]

It consists of a laminated endless metal band and a number of block bodies each having a mounting groove on the top for attaching the metal band.The block body has a curved protrusion projecting outward on one side thereof, and a curved convex portion protruding outward on the other side. forming a curved recess of a similar shape into which the curved protrusion can be slidably fitted, and further making the surface of the mounting groove in contact with the inner surface of the endless metal band a curved surface continuous from the curved protrusion to the curved recess; 1. A driving device for a belt type continuously variable transmission mechanism, characterized in that the block bodies are directly connected to each other by fitting into a curved convex part and a curved concave part, and are arranged continuously in an endless metal band.
